FR-400 Ultra Heavy-Duty (UHD) Desoldering Station

List Price:

The Hakko 300W FR-400 Ultra heavy duty desoldering station is specifically designed for the difficult rework of extremely large mass components where a significant amount of thermal inertia must be overcome. An excellent tool for desoldering the most challenging solder joints.

This part number has been replaced by FR400-53.


300W Heating Element with a top Controlled Temperature of 940°F (500°C)
The high mass of the heater and nozzles combined with the power and control of the composite ceramic heating cartridge allows for rework of some of the most challenging solder joints at only 750°F (400°C) and without preheating!

The anti-clogging features help ensure instantaneous application of peak vacuum pressure to the solder joint, and prevent the premature release of the vacuum system before the solder has cleared the heater and is captured in the solder collector chamber.

Large Solder Collection Chamber
The solder collection chamber is 3X larger in capacity than other Hakko desoldering stations, and it can be cleaned and re-used, reducing environmental waste.

Large Easy-to-Read Display
The display includes a vacuum indicator that lets you know if there are any restrictions building that will need to be cleaned out using the tools that are in the maintenance kit (included with the station.)
